Dell OptiPlex 3011 AIO Statement of Volatility - Page 2

Description Reference Designator RTC CMOS BATTERY Volatility Description Volatile Battery back-backed CMOS memory 256 bytes Stores CMOS information User Accessible for external data No Remedial Action (action necessary to lose data) Removing the on board Coin Cell battery Video memory UMA architecture- Volatile memory in off state. No - type - see next column uses system DDR3. UMA uses main system memory size allocated out of main memory. GPU architecturegDDR3. Volatile memory in off state. No GPU uses only. Four modules will be populated. System memory size is 1 GB. Hard drive User replaceable Non Volatile magnetic media, Yes various sizes in GB Enter S3-S5 state below. Enter S3-S5 state below. Low level format CD-ROM/RW/ User replaceable Non Volatile optical/magnetic Yes DVD/ media DVD+RW/ Diskette Drives Low level format / erase CAUTION: All other components on the system board lose data if power is removed from the system. Primary power loss (unplugging the power cord and removing the battery) destroys all user data on the memory (DDR3, 1067 MHz). Secondary power loss (removing the on-board coin-cell battery) destroys system data on the system configuration and time-of-day information. In addition, to clarify memory volatility and data retention in situations where the system is put in different ACPI power states the following is provided (those ACPI power states are S0, S1, S3, S4 and S5): S0 state is the working state where the dynamic RAM is maintained and is read/write by the processor. S1 state is a low wake-up latency sleeping state. In this state, no system context is lost (CPU or chip set) and hardware maintains all system contexts. S3 is called "suspend to RAM" state or stand-by mode. In this state the dynamic RAM is maintained. Dell systems will be able to go to S3 if the OS and the peripherals used in the system supports S3 state. S4 is called "suspend to disk" state or "hibernate" mode. There is no power. In this state, the dynamic RAM is not maintained. If the system has been commanded to enter S4, the OS will write the system context to a non-volatile storage file and leave appropriate context markers. When the system is coming back to the working state, a restore file from the nonvolatile storage can occur. The restore file has to be valid. Dell systems will be able to go to S4 if the OS and the peripherals support S4 state. S5 is the "soft" off state. There is no power. The OS does not save any context to wake up the system. No data will remain in any component on the system board, i.e. cache or memory. The system will require a complete boot when awakened. Since S5 is the shut off state, coming out of S5 requires power on which clears all registers.
